Nate's trick for calulating squares

From Nate:

Lets say you want to know the answer to 8 x 8? (or any N x N)
Well, if you know that 7 x 7 = 49 (or any ((N-1) x (N-1))
you can just add (7 + 8) + 49 = 64 = 8 x 8 (or use any ((N-1) + N)

We tried it for lots of N's & It works!

Nate, you blew our minds when you announced that you had figured out a pattern in numbers one day when riding in the car!
